Maybe you solved the problem in the meantime, otherwise I recommend to
use the solution below, which I use in my app - without the if
condition with break - and works fine

NSAutoreleasePool* outterPool = [[NSAutoreleasePool alloc] init];
NSDictionary* userDefaults = [NSUserDefaults standardUserDefaults]
importantValue = [[userDefaults objectForKey:@"myKey"] boolValue];
while (1)
{
NSAutoreleasePool* innerPool = [[NSAutoreleasePool alloc] init];
if (![self threadMustExit])
[self doStuffWith:importantValue];
if (![self threadMustExit])
[self doMoreStuff];
if (![self threadMustExit])
[self doEvenMore];
[innerPool release];
if ([lock lockWhenCondition:kConditionThreadMustExit])
{
[lock unlock];
should be here: [innerPool release];
break;
cause after break, the innerpool would otherwise not be released
}
and set it here: [innerPool release];
}
[lock lock];
[lock unlockWithCondition:kConditionThreadIdle];
[outterPool release];
}
This crashes the second time through the loop (when innerPool is being
created for the second time). Why?
I need to drain the pool each time through the inner loop. I am not
using
Garbage Collection.
